Yes, I saw in the comments that the Youtube engine is only going to run a single down draft Weber, that just makes all the other modifications seem even more strange!
As you said, to each their own.
Greg Margett's clutch modification was to machine off the deep rim of the original flywheel, (which has the additional benefit of lightening it) and re-drill/tap new holes
for a larger diameter diaphragm clutch. The original bronze spigot bush was also changed to a suitable bearing. Of course this also means changing the release bearing
and modifying the operating fork slightly.
Greg used to sell all the parts needed for this conversion and I believe the clutch pressure plates were specially made to his specs. In the past he had also experimented
with fitting stronger coil springs in the original clutch, to stop it slipping on tuned engines. The results weren't very good however and resulted in a very snatchy engagement
which he thought would soon break the transmission.
